HINGE.

Specification of Letters Patent.

Patented June 19,1917.

Application filed December 4, 1915. Serial No. 64,959.

To all whom it may concern:

Be it known that I, ULYssns G. MOQUEEN, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Hinges, of which the following is a specification.

This invention relates to hinge structures.

An object of the invention resides in the provision of a structure of this character which will be designed particularly for use in connection with vertically movable bodies or objects such as easements, doors and the like and one which may be used in combination with a lifting mechanism such as the one shown in my copending application filed April 1, 1915, Serial Number 18,608 and I wish particularly to emphasize such features of construction of the device which will operate to hold the casement against moving in a vertical direction when the casement is opened and one which will further operate to permit the casement to be operatively lowered when returned to its closed frame.

In carrying the invention into practice it is found that in order to relieve the hinge pintle from unequal strains, it is necessary to incorporate with the device a means for positively locking the hinge against sliding movement by direct locking contact with one of the leaves thereof at a point respectively between the sides and the ends of the same.

As a further and desired object in view the hinge structure consists of companion relatively swinging leaves and an attaching plate, the latter being operatively associated with one of the leaves and designed with a view to facilitating its application to the object from which the casement is to be supported and without the necessity of removing the plate fromthe hinge at such time.

A further object of the invention resides in the construction of locking mechanism which will be simple, strong and durable and positive in its operation to hold the casement against being lowered accidentally when opened and one which will always permit operative sliding movement of the casement in the frame when in a normal closed position.

Another object of the invention resides in the provision of a hinge structure which may be applied to the easement and to the frame in the manner common to the application of any ordinary hinge thereto and one which will be ornamental and attractive when applied.

In the drawings Figure 1 is a sectional perspective view of a casement and its frame showing the application of the hinge structure thereto and its association with a lifting mechanism.

Fig. 2 is a side view of the hinge structure showing its application to the casement and to the frame and further illustrating the raised position of the structure.

Fig. 3 is a similar view showing the hinge structure lowered.

Fig. 4 is a horizontal section taken on the line 14 of Fig. 2.

Fig. 5 is a vertical section through the hinge showing the same in its looked position and further illustrating conventionally, the position of the striking element to the locking means so as to cause a release of the latter on the closing of the casement.

Fig. 6 is a similar view showing the striking element in its normal position relatively of the locking means.

Fig. 7 is a horizontal section through a portion of the attaching plate and one of the hinge leaves.

Fig. 8 is a side elevation of the attaching plate.

Vith a view to embodying a number of elements all constituting a hinge structure, capable of being applied to the casement and to the frame, much in the manner of applying an ordinary hinge and at the same time furnishing means whereby the casement may he operatively raised and lowered at the requisite times, I make use of two leaves 1 andQ, the former being provided. with knuckles 3 3 which are alined with similar knuckles 4. 1f+. upon the leaf 2. All of these knuckles are adapted to receive any well known form of hinge pintle The hinge structure is used in connection with the lifting mechanism 6 conventionally illustrated in Fig. 1 and fully referred to in my mentioned co-pending application. However it is briefly stated that this improved hinge structure is used upon a casement A which is adapted to move in a vertical direction ina frame 13. It is customary to move the easement vertically for the purpose of permitting the lower edge thereof to freely pass over a stop strip C during the operation of opening and closing the casement in the frame. In view thereof the hinge leaf 2 is provided at one side with a plurality of studs 7 having shanks 8 which extend through guide slots 9 in an attaching plate 9" and as illustrated, they are provided with guide heads 10 which coact with the under-cut walls 11 of said guide slots to permit the hinge to be raised or lowered from the attaching plate as will be fully understood. The attaching plate and said leaf 2 are extended in a mortise 12 in the frame B and as illustrated, that portion of the leaf which extends into the mortise has a length less than the length of the attaching plate in order that sliding movements of the hinge can be properly accommodated. This construction is desired for the further purpose of exposing portions of the attaching plate in order that the holes 1313 may be exposed when it is desired to extend fastening screws or the like 14 therethrough at the time of attaching the structure to the frame B. It is evident on'reference to Fig. 2, that when the hinge structure is raised, the opening 13 at the bottom of the attaching plate may be exposed, while when the hinge is in the lowered position shown in Fig. 3, the opening 18 at the top of the plate will be exposed.

With a view to preventing the easement from being lowered until the same is in a full closed position, I provide a spring bolt 15 slidable in a casing 16 carried by the attaching plate. The spring bolt is provided with a stem 17 which freely slides through a guide passage 18 in one end of the casing. Exteriorly of the casing, the stem is provided with a stop 19 for preventing the keeper from being wholly ejected from the casing under the action of the spring 20. The spring 20 operates to yieldably present the bolt against one side of the hinge leaf 2. Said hinge leaf is provided at a point, respectively between its ends and sides with a keeper passage 21 which is arranged in the same vertical line with the keeper so that the latter will be free to extend thereinto when the hinge is adjusted to the position shown in Figs. 2 and 4C. The hinge leaf 1 is provided with'a releasing lug 22 disposed in the same horizontal line with the passage 21 whereby to enter the same when the leaf 1 is closed against the leaf 2. By causing the lug to enter the keeper passage 21when the leaf 1 is closed against the leaf 2, it follows that the keeper 15 will be automatically retracted and forcibly extended to a point where it will be free to slide against the inner surface of the leaf 2. From the foregoing description it is seen that the easement is normally free to be raised and lowered in the frame. When the mechanism 6 is operated to cause the case ment to move in an upward direction, the spring bolt 15 will of course, be projected into the passage 21. The casement is then rigidly held in a uniform horizontal position above the stop strip C and it may be freely moved over the strip. The structure is simple, comparatively inexpensive, and durable. By looking the leaf 2 at a point respectively between the sides and ends thereof, the strain upon the pintle 5 is uniformly distributed and the hinge is consequently held againstcanting. This insures accuracy toward maintaining the casement in the same uniform position above the stop strip when the former is raised. The hinge structure is further of such peculiar design as will not detract from the general beauty of the easement and in fact stimulates a structure corresponding with that of an ordinary hinge. It may also be applied to the easement and to the frame, much, in the manner of that method commonly employed in attaching the well known hinge.

As an additional means of securing the attaching plate to the frame B, an intermediate opening 28 is formed in the plate and said opening is adapted to aline with the passage 21 as shown in Fig. 3 when the hinge is in its normal position. This is .preferred in order that a fastening screw 24 may be extended through said passage and into the frame. I

What is claimed as new is v A hinge structure for casement lifts comprising, an attaching plate adapted to be secured to the frame, hinge leaves slidably supported from said plate, one of the leaves having a keeper opening therein, a bolt adapted to be mortised in the frame and freely working through said attaching plate and normally held retracted when the hinge leaves are lowered and through direct sliding contact of one of the leaves with said latch, the said bolt being adapted to enter the keeper opening when the hinge leaves are raised upon said attaching plate, RDClIIlGQDS projecting from one face of the other leaf and adapted to enter the keeper opening and to retract the bolt from said opening when the leaves are closed together and thereby permit said leaves to freely slide from said plate.

In testimony whereof I afiix my signature in presence of two witnesses.
